Challenging course, great volunteers, fun for all ages! This is the third year I’ve run Brea and it’s one of my favorites. This year they changed the course so there’s quite a bit of elevation change, mostly in the middle milles. There are plenty of enthusiastic spectators at the finish. Registration and packet pick-up is a breeze, and there’s tons of parking, making this a pretty stress-free race. Post race is noisy, crowded, people bumping into you, but good food.
